Does one need to use XP Pro in order for a P4 with hyperthreading to work
right? Right now I have XP Home. Hyperthreading is enabled in my bios but
when I am doing something heavy like processing a movie or defragging, it
takes a long long time to open another program or IE window. I thought
hyperthreading would allow you to do 2 things at the same time.

I don't think that HT was intended for defragging operations. To avoid
hard drive errors I recommend defragging with no other software running.
As for the movie issue, that may be caused by insufficient amount of
hard drive swap file space or RAM.

According to Intel you have to have an operating system that supports
Hyper-Threading technology (HT).

Here are some things that you might try (at your own risk, read
carefully too).

HTH (c:
 
XP Home DOES support HT CPUs, you do not need PRO.

Open Device Manager (control panel | system | hardware tab | device
manager button), look at "processors" branch. If HT is detected and
working you will see two processors listed, else just one. The "computer"
line will also read "multiprocessor" rather than "uniprocesor".
